Tabloids have tutted for at least a week that Keibler was with child after someone snapped a picture of her out wearing a fitted dress with what could have been a protruding tummy. But if anyone was wondering if the model/dancer/former wrestler was really carrying George Clooney's love child, she seems to have put the definitive kibosh on that.

In what has to be a light thumbing of the nose at the rumor mill, Keibler released a photo Wednesday that all but screamed: Baby bump? What baby bump?

The photo shows Clooney's girlfriend working out -- apparently in Italy where she and the actor have been vacationing. She's wearing a bra top with low slung pants to show, in no uncertain terms, that she's not only not carrying a child, she's carrying nary a drop of body fat.

She coyly released with picture with only the statement, "I am officially on Instagram!"

One of her Twitter followers gushed, "after that picture, it should be called Insta-abs! WOW!

If you're looking for any deep, revealing information about Stacy Keibler, something beyond the blonde hair and the 42-inch legs, you won't find it in the latest issue of Men's Fitness where she's both cover girl and cover story.
